Review Summary

Great job on implementing the createTree function! Your recursive solution is clean, well-structured, and meets all the requirements of the task, so I am happy to approve it.

As a point of improvement for future projects, consider making your for...in loop more robust. This loop can sometimes iterate over inherited properties from an object's prototype. You can prevent this by adding a check inside the loop, like this:

if (Object.prototype.hasOwnProperty.call(data, key)) {
  // your code here
}

This is a best practice that makes your code safer. Overall, excellent work on this submission!

The for...in loop iterates over all enumerable properties of an object, including those inherited from its prototype. This can sometimes lead to unexpected items in your list. To make your code more robust, it's a good practice to check if the property is directly on the object. You can do this by adding a condition like if (Object.prototype.hasOwnProperty.call(data, key)) { ... } inside your loop.
